| For example, in the case of "Let's make a square", we will make the most stable shape mentally. If some condition were given from various aspects, will that shape change? People may better understand when the shape is stable in those conditions. And, it will give us a good situation to think "How to make a certain shape given certain conditions", when those conditions are related to the shape. Furthermore, there are some cases where many possible shapes can be made. Then, what should you call such cases? This will become a good opportunity to express possible sets in words. |
